Question

A round pizza with a 14" diameter is cut into 8 congruent slices. What is the area of one slice/sector? (in termsof pie)

Answer 1

So, we know:

Diameter =14

Radius =7 (Half of the diameter)

$\text{Area}=\pi r^2$$\text{Area}=\pi(7in)^2\text{ =49}\pi in^2$

Now we divide by the number of slices to get tha area of the slice:

$\frac{49\text{ }\pi\text{ in}}{8}\text{ = }\frac{49}{8}\text{ }\pi in^2$

So the answer is b.
